Store stock will vary but I picked up a Ninja Master Prep Advantage for $50 in-store down from around $170(although I see $80 elsewhere http://pricespy.co.nz/product.php?pu=2515534), they had three on the shelf at the time.
Farmers can have good clearance deals as they really don't like old stock so its worth checking out there online clearance products or in-store. Of note online at the moment is:
Goldair Wonder Chef Kitchen Prep Machine FES150 $30 ($55 on clearance at mightape) http://www.farmers.co.nz/electrical/electrical-clearance/gol…
Russell Hobbs Colour Control Iron 19840AU $80 (also $80 at briscoes) http://www.farmers.co.nz/electrical/electrical-clearance/rus…
Tilly@home Water Bottle 'Body' $1 http://www.farmers.co.nz/home/home-clearance/tilly-home-wate…
The Russell Hobbs Iron is the same price at Briscoes. That might be more convenient for some people.
